AT311_WN_E1 What’s New in Atoll 3.1.1

What's New in Atoll 3.1.1Several new features and changes have been introduced in the version of Atoll 3.1.1 made available on February 17, 2012. These new featuresare described below. The new features introduced in the previous releases of Atoll 3.1.1 and 3.1.0 are described later in this document. For moreinformation on any of these features, see the online help, the User Manual, the Administrator Manual, and the Technical Reference Guide.

New Features Introduced in Atoll 3.1.1 (Build 4286)General Features

Working Environment• Some fields listed under "Legend" in the Table tab of the Properties dialogues are followed by:

• "(NOT USED)" to indicate that the field is not used in the current release of Atoll. The corresponding column is hidden by defaultwhen Open Table is used.

• "(OBSOLETE)" to indicate that the field is not available and will be removed in future releases of Atoll. The corresponding columnis not available when Open Table is used.

Antennas• The linear interpolation in antenna patterns is now calculated in Watts by default.

3GPP Multi-RAT NetworksWorking Environment• User Interface

• In Multi-RAT documents, remote antennas are now identified as "SiteX_T_Y_RemZ" and "SiteX_T_Y_RepZ" where "X" is the donor sitenumber, "Y" the donor transmitter number, "Z" a number assigned to the remote antenna or to the repeater when it is created, andwhere "T" describes the technology (GSM, UMTS, or LTE) in the corresponding tip text.

Automatic Cell Planning• The ACP now includes a multi-storey extension where evaluation points are distributed on all floors of buildings over a minimum height

that are defined in a clutter heights map. The creation of evaluation points on all floors enables the ACP to take all floors of the buildinginto account during optimisation.

• By defining an option in the acp.ini file, the ACP can display advanced cost options which enable the user to define the maximum numberof changes to be made (either as a value or a ratio) and to change the ranking of the order of cost in the final implementation plan: changeswith the lowest cost are performed first and changes with the highest cost are performed last. Additionally, if the maximum number ofchanges is defined as a ratio, the user can define an option enabling him to use the number of transmitters in the focus zone instead ofthe computation zone.

• By defining an option in the acp.ini file, new predictions, showing the initial and final coverage of each antenna, are available.• By defining an option in the acp.ini file, a new prediction, showing the weight used for the traffic and for each zone, is available.• By defining an option in the acp.ini file, new predictions, showing the initial and final coverage by transmitter, are available.• By defining an option in the acp.ini file, the weight between quality and the implementation cost can be defined.• Decimal values can now be used for electrical tilt, mechanical tilt, azimuth.• By defining an option in the acp.ini file, the ACP can optimise electrical tilt using a defined range from the current electrical tilt.• The ACP now enables the user to compare the results of one optimisation with the results of another optimisation from the same setup

or from a different setup. The results, along with the variations between the two optimisations, are displayed in the Properties dialogueof the comparison.

• It is now possible to share path loss or incidence matrix information by defining a shared directory. The ACP first searches the shareddirectory for the information and then, if not found, in the private directory of the user. The information in the shared directory is updatedby a single user with administrator rights.

• It is now possible to sort table contents when the Show advanced table option is selected.

GSM GPRS EDGE NetworksWorking Environment• User Interface

• A new key performance indicator, Final Blocking Probability (%), has been added in the Traffic Data view of the Subcells table. ThisKPI is calculated using a traffic capture and the AFP module, and is also part of a simplified traffic model used by the AFP module.

• In the corresponding tip text, remote antennas are now identified as "SiteX_Y_RemZ" and repeaters as "SiteX_Y_RepZ" where "X" isthe donor site number, "Y" the donor transmitter number, and "Z" a number assigned to the remote antenna or to the repeater whenit is created. In Multi-RAT documents, they are identified as "SiteX_T_Y_RemZ" and "SiteX_T_Y_RepZ" where "T" describes thetechnology (GSM, UMTS, or LTE).

New Features Introduced in Atoll 3.1.1 (Build 4191)General Features

Working Environment• User Interface

• Window tabs of different documents are now displayed using a separate colour. You can therefore recognize window tabs belongingto the same document by their colour.

• In order to avoid very long window tabs, window tab titles longer than approximately 40 characters are truncated. The complete titleis visible in a tool tip displayed when the mouse is placed over the window tab. The tool tip also displays the path to the ATL file towhich the window belongs.

• You can now display the map scale in the map window.• In table views, frozen columns are now separated from other columns with a vertical red line.• You can increase the width of the clutter description pane in the Status bar (bottom right), to display the descriptions of clutter classes

with long names, using an option in the Atoll.ini file.• In the Print Setup, page margins are now editable in inches or millimeters depending on your computer’s regional settings.• Find on Map has been moved from the Edit menu to the Tools menu.• The map can be moved in the map window by clicking the mouse wheel and dragging it in the desired direction.• With the Site Configuration window, Atoll now displays all transmitters, sorted by technology, on a selected site. The properties of

each transmitter can be viewed by double-clicking the transmitter in the Site Configuration window.• When displaying a histogram, Atoll now enables the user to zoom in on a part of the histogram by selecting the range of values of

interest in the accompanying list.

• User Configurations

• You can now save and load the map centre and zoom level to and from user configuration files.

• Tables

• You can now export data tables, or selected columns, to XML Spreadsheet 2003 files (XML). You can open XML Spreadsheet 2003 filesin MS Excel 2003 and later. Unlike XLS files, XML Spreadsheet files are not limited to 65,536 rows and 256 columns.

• During XML file export, antenna patterns are now exported in text format instead of the binary format.

4


• Find and Replace functionalities have been added to standard Atoll tables.

• By setting an option in the Atoll.ini file, you can instruct Atoll to always use a defined database type (MS Access, SQL Server, or Oracle),and not display the database selection dialogue that appears when creating a new document from an existing database or when exportinga document to create a new database.

• Using options in the Atoll.ini file, you can automatically run the GSM subcell audit when opening a document from a database orrefreshing data from the database.

• Atoll now supports the use of JPG files when exporting or importing graphic files.• Reception can now be measured in V/M (volts per metre).• The user can now create zones (computation, focus, hot spot, printing, and geographic export) as either polygons or rectangles.

Antennas• Atoll now enables you to set the display scale of antenna pattern diagrams.• Atoll now supports smart beam antennas (i.e., dual beam antennas, variable electrical azimuth antennas, etc.). The Antenna Selector tool

and the display mode of transmitters have been enhanced in order to be able to model transmitters equipped with such antennas.

Coverage Predictions• Coverage prediction reports can now be exported as text files or as Excel spreadsheets.• When calculated by value intervals, the results per pixel of most coverage predictions can now be exported to a text file.• The display of coverage predictions has been improved. Atoll can now centre one or all predictions in the map window or automatically

adjust the zoom level to display the entire area covered by one or all predictions.• Atoll permits the user to create sub-folders in the Predictions folder, thereby allowing the user to organise the coverage predictions

according to any criteria.

Network Planning• When displaying neighbour relations on the map, the transmitter whose neighbours are to be displayed can now be selected in the

Network explorer, on the map, or in the Neighbours table. When the transmitter is selected in one of the three (i.e., the Networkexplorer, the map, or the Neighbours table), Atoll then centres the display of the transmitter in the other two.

3GPP Multi-RAT NetworksNetwork Planning• Coverage Predictions

• A multi-RAT prediction has been introduced. Using this prediction, you can display the areas where a specific service can be obtainedfor a given terminal and mobility:

• in DL for GSM• in DL and in UL for UMTS and LTE.

• Resource Allocation

• The GSM AFP is now able to allocate BSICs by considering inter-technology neighbours. As an example, the GSM AFP will try not toallocate the same BSIC for two GSM transmitters which are neighbours of a common UMTS (or LTE) cell.

• The Scrambling Code allocation is now able to consider inter-technology neighbours as new constraints. As an example, the algorithmwill try not to allocate the same scrambling code for two UMTS cells which are neighbours of a common GSM transmitter (or LTE cell).

• The Physical Cell ID allocation is now able to consider inter-technology neighbours as new constraints. As an example, the LTE AFP willtry not to allocate the same Physical Cell ID for two LTE cells which are neighbours of a common GSM transmitter (or UMTS cell).

GSM GPRS EDGE NetworksNetwork Capacity• CW Measurements

• Atoll now permits you to save the settings as a configuration when using the Filtering Assistant to filter points on a CW measurement.The same configuration can then be selected and reapplied.

Atoll AFP• The number of graph lines representing the cost value in the AFP progress interface has been increased. In addition to the total modifiable

cost, the modifiable BCCH cost is displayed, when the BCCH is being allocated. If the number of allocated TRXs is being optimised, theadditional cost displayed is the blocking cost (which is the main parameter that the AFP tries to optimise when allocating TRXs). Inaddition, the way the modifiable cost is displayed has been modified in order to avoid displaying misleading intermediate values and toprovide a clearer understanding of the value variations.

• A reuse distance can now be defined when allocating channels and BSIC in the GSM AFP.

Automatic Cell Planning• The cost of each change can now be set as a financial cost instead of as a ratio.• Repeater amplifier gain can now be imported directly into an ACP optimisation by creating custom fields in the Repeaters table in Atoll

and then defining the custom fields in the acp.ini.• The ACP now permits the definition of a custom resolution on zones used in an optimisation.• The ACP now permits the use of custom fields of secondary antennas as initial input for the optimisation of secondary antennas.

UMTS HSPA NetworksNetwork Planning• Service Modelling

• Atoll now supports HSPA variable bit rate services.

• Coverage Predictions

• In order to display a pilot signal level predictions for a given terminal (and considering its gains and losses), service, mobility andcarrier, a new display field has been added in the Pilot Quality Analysis predictions. In addition to the standard Ec/Io and Ec/Io margins,you can now display the received pilot signal strength Ec (in dB) on each pixel.

Network Capacity• CW Measurements


• Radio Resource Management and Simulations

• The method for calculating average cell throughput during simulations has been improved. Now, only cells with actual HSUPA usersare taken into consideration when the average HSUPA throughput per cell is calculated. Cells without HSUPA users are not taken intoconsideration.



LTE NetworksNetwork Planning• Network

• The cell layer priorities have been reversed to homogenize the priorities with the service definition and with the GSM HCS layerpriorities. Now, 0 signifies lowest priority as opposed to the highest in previous versions. If you are working with multi-celltransmitters, you may have to assign layer numbers to cells again in order to be consistent with the previous versions. If you wish tocontinue working as before, you can keep the previous layer priority setting by adding an option in the Atoll.ini file.

• You can set the minimum number of frequency blocks for the calculation of the uplink allocated bandwidth to a value higher than 1(default) through an option in the Atoll.ini file.

• The downlink interference calculations have been improved. Instead of an average interference level calculation for the followingthree channels: RS, PDCCH, and PDSCH, Atoll now calculates the exact collision between the resource elements belonging to differentsignals and channels. The frequency-domain positions of the resource elements used for reference signal transmission depend on thecells’ physical cell IDs. This is called RS hopping or v-shifting. This aspect is now fully taken into account for calculating downlinkinterference between different signals and channels. Atoll now calculates and stores separate values of interference levels for RS, SS/PBCH, PDCCH, and PDSCH.


• You can calculate the EIRP from Reference Signal EPRE instead of reference signal power when calculating signal level-based coveragepredictions through an option in the Atoll.ini file. With this option, a Coverage by Transmitter will display the RSRP values.

• Interference Matrices

• Interference matrices can now be exported to and imported from text files with IM2 extension. This is the same format as the oneavailable for GSM interference matrices.

• Inter-technology Interference

• You can model the effect of interference from external networks working under another technology (CDMA, TDMA or OFDM) orexternal sources.

• In addition to the possibility of setting the inter-technology DL noise rise level for each cell to model the effect of interference fromexternal mobiles on your network in the downlink, you can set inter-technology interference reduction factors to model the effect ofinterference from external transmitters (of a linked project in co-planning) on your network in the downlink.

• Inter-technology interference affects all interference-based calculations.

Network Configuration Using the AFP• For automatic physical cell ID planning, Atoll now facilitates the management of physical cell IDs by letting you create domains, each

containing groups of physical cell IDs.• The uniform distribution strategy is now available in the AFP dialogue, instead of the option in the Atoll.ini file. The Atoll.ini file option still

works for the "basic" physical cell ID allocation.

• Monte Carlo Simulations

• Calculations in the Monte Carlo simulations are now performed for inactive users as well.• Inactive users can be connected in downlink, uplink, or downlink and uplink, or rejected similar to active users.

If you wish tocontinue working as before, you can keep the previous layer priority setting by adding an option in the Atoll.ini file.

• You can set the minimum number of subchannels for the calculation of the uplink allocated bandwidth to a value higher than 1(default) through an option in the Atoll.ini file.

• Neighbour Planning

• Depending on the best server selection method defined in the network settings, the automatic neighbour allocation can be based oncoverage areas calculated for best servers based on the preamble C or the preamble C/(I+N).


• Interference matrices can now be exported to and imported from text files with IM2 extension. This is the same format as the oneavailable for GSM interference matrices.

Network Configuration Using the AFP• For automatic preamble index planning, Atoll now facilitates the management of preamble indexes by letting you create domains, each

containing groups of preamble indexes.• The uniform distribution strategy is now available in the AFP dialogue, instead of the option in the Atoll.ini file. The Atoll.ini file option still

works for the "basic" preamble index allocation.

• Monte Carlo Simulations

• Calculations in the Monte Carlo simulations are now performed for inactive users as well.• Inactive users can be connected in downlink, uplink, or downlink and uplink, or rejected similar to active users.



Network Settings• You can select whether to calculate best servers based on the preamble C or the preamble C/(I+N).

Microwave Link Networks• Recommendation ITU-R P.530-13 is now supported.

Semi-automatic Channel Allocation• Different options are now available for defining the interfered bandwidth in the interferer filter for semi-automatic channel allocation:

Co-channel only, User-defined percentage, Fixed guard band, or No filter.

Climatic Data• The Vigants climate zone for the Great Lakes region of the US is now supported.

• The Vigants model now uses a composite margin instead of a flat fade margin.

Equipment• In the interests of forward compatibility, the limitation of 10 channels per connection has been removed in order to accommodate the

complexity of both current and future microwave installations.

• A new type of wave guide, the "Flex twist," has been added.

• Atoll now supports equipment files in the Pathloss 5 format.

Reports• Under the "Global Estimation for an Entire Year" section, the Analysis Report on a link can now give the cut off duration including

equipment failures and the percentage of non-cut off including equipment failures.

• The Analysis Report has been reorganized to better present the information contained within and to adhere more closely to terminologyused elsewhere in the industry. In addition, a new report Design Summary is now available; it contains the main quality and availabilityresults of the microwave link.

Network Planning• The link frequency can now be recalculated directly from the Links table, thereby enabling the user to recalculate frequency for a selected

group of links at the same time.

New Features Introduced in Atoll 3.1.0 (All Released Builds)General Features

• You can now prevent users from modifying the microwave links calculation settings in the user interface.

Working Environment• User Interface

• Atoll 3.1.0 presents an entirely re-designed user interface. The user interface respects the radio planning process while at the sametime following the best of current ergonomic design. The flexibility of Atoll's new user interface puts the user's needs first. The usercan rearrange Atoll's windows and tools to best suit the task at hand and can choose which toolbars to display. Atoll 3.1.0 also offersa full-screen mode, enabling the user to hide everything except the map window and the current tool.

Atoll 3.1.0 offers the user:

• A new, modern design• Tabbed windows to facilitate work on multiple projects or multiple tables within one project• A customisable workspace• A full-screen mode, enabling the user to maximise the working area when working with the map window.• A re-designed Explorer window with a Data tab dedicated to project data, a Geo tab for all geographic data, and a Parameters

tab to configure equipment and modules.

• The map window display can be adjusted on the area of any group of sites, transmitters or any map as well as by using "Centre in MapWindow" to centre the selected object in the window

• "Centre in Map Window" has been improved and is now available from the context menu of any record in the Sites and Transmitterstables.

• Atoll now enables the user to reset the workplace display to its default settings.

• The vector editing tools have been improved. It is now possible to create a new polygon from existing polygons using the union,intersection and difference tools.

• Tables

• Along with other methods of navigating through data tables, Atoll now permits the user to navigate through tables embedded informs using the mouse wheel (for example, the Cells tab of the transmitter properties dialogue).

• When defining a choice list in the properties of a table field, you can now choose whether the field should only accept values in thechoice list or whether it should allow users to enter values other than those in the choice list.

Units• The user can now choose to display temperatures in Fahrenheit.

Geographic Data• Atoll now supports the https protocol for web map server URLs.

Radio Antennas• Atoll now enables the user to group the antenna models belonging to the same physical antenna. A new field called "Physical Antenna"

is available in the antenna properties. It is the name of the physical antenna to which an antenna model belongs. A physical antenna canhave one or more antenna models (patterns), corresponding to different electrical downtilts.

• An antenna selection assistant is now available. Based on physical antennas and electrical downtilts, the antenna selection assistantproposes a list of antenna models available for use.

• Physical antennas that are no longer used can now be flagged as obsolete by adding the word "obsolete" (not case sensitive) to the nameof the physical antennas. Physical antennas flagged as obsolete are not listed among available antennas in the antenna selection assistant.

• The additional electrical downtilt can be made accessible in the GUI by setting an option in the atoll.ini file.

Propagation Calculations and Path Loss Matrices• A new optional propagation model called Crosswave and developed by Orange Labs is now available for Atoll. Using the experience of

Orange in terms of propagation and measurements from various environments and frequency bands, this model which is fully compatiblewith Atoll can provide very accurate results with its default calibration. Like any propagation model, this model can be retuned whenadditional data is added to the project (detailed maps, real measurements, etc.).

• The size of existing path loss matrices can now be optimised in order to keep only significant values. Matrices can now be limited by settingthresholds in order to store only signal levels that meet these user-defined thresholds.

Coverage Prediction Reports• The user can set the number of decimal places to be displayed following the decimal in coverage prediction reports by setting an option

in the atoll.ini file. • You can change the reference hot spot surface area in coverage prediction reports by setting an atoll.ini option.

9


Coverage Prediction Export• It is now possible to export only the visible layers (levels) of some coverage predictions by setting an option in the Atoll.ini file.

API and Atoll Development Kit• You can now disable the macro timeout, i.e., no timeout, by setting it to 0 when adding a macro to Atoll.• The default macro timeout has been increased from 16 hours to 24 days. This default value is used when the timeout parameter is left

empty.• For LTE and WiMAX Coverage by C/(I+N) (DL), Coverage by C/(I+N) (UL), Service Area Analysis (DL), and Service Area Analysis (UL)

predictions, it is now possible to export the actual calculation results for each pixel to a text file.

RAT networks are stored in a single Atoll document and database.• It is possible to select the radio access technologies to include in a 3GPP Multi-RAT project when creating a new document based on this

template.• It is possible to allow or deny access to the radio access technologies available for inclusion in a 3GPP Multi-RAT document through

options in the Atoll.ini file.

Network Planning• Network

• A single Sites folder is available on the Network tab. These sites can be used for transmitters of any radio access technology modelledin the multi-RAT project.

• There is a Transmitters folder for each technology modelled in the multi-RAT project. The commands available in their context menudepend on the technology and are the same as the ones available in each individual single-RAT template.

• Atoll permits the user to designate an antenna as "shared" between technologies in a multi-RAT or co-planning project. When theantenna is designated as shared, any changes made to its height, azimuth, etc., in one technology are synchronised in the othertechnology.


• Just like in single-RAT project, predictions can be created from the context menu of the Predictions folder. The default coveragepredictions present in the Prediction Types dialogue are identical to the ones available in each single-RAT project template.

• You can also create new predictions from the context menu of the Transmitters folder for each radio access technology modelled.


• Neighbour tools are available from the context menu of the Transmitters folder for each radio access technology modelled. From anytechnology, you can assign, either manually or automatically, neighbours of the same technology or from any other one.

• Frequency and Parameter Planning

• Depending on the selected technologies, the resource allocation tools available in the multi-RAT project are identical to the onesavailable in each mono-RAT project template: frequencies, BSICs and HSNs for GSM, scrambling codes from UMTS and physical cellIds and frequencies for LTE.

• Using Find on Map, the reuse of any technology-specific resource can be analysed in detail on the map.

Network Capacity• Traffic Model

• In a multi-RAT project, multi-service parameters are managed in a single Traffic Parameters folder on the Parameters tab. Anyservice, mobility type, or terminal can be used and set up for any technology modelled in the multi-RAT project.

• Services can be defined for any technology modelled in the multi-RAT project. The parameters available depend on the technologymodelled. For each service, technologiesintermodulation are ranked from the highest priority to the lowest. The network will then tryto attach a service on the technologies with the highest priority.

• The technologies modelled can be supported by terminals. The parameters available depend on the technology modelled.

• Traffic Maps

• In order to model the necessary traffic for simulations, all traffic maps are available in the Traffic Maps folder on the Geo tab.

• Geographic Data

• In a multi-RAT document, Atoll permits setting values specific to each technology in the properties of the clutter classes.

• Radio Resource Management and Simulations

• Multi-RAT simulations are supported. These simulations model how a network subject to multi-technology traffic would manage itsresources in order to absorb a maximum of traffic without exceeding defined permitted loads.

Network Optimisation Using the ACP• The definition of optimisation objectives has been redesigned in the ACP, enabling the user to weight individual objectives and to use

different sources of traffic data for each objective. Additionally, the ACP enables the user to define complex optimisation objectives,combining several quality measurements.

10


• The ACP now enables the user to define a wide variety of optimisation-independent settings from within Atoll, eliminating in most casesthe need to manually edit the acp.ini file.

Drive Test Data• Drive tests of any technology can be imported and managed in multi-RAT projects in order to verify the quality of the real networks and

to analyse it in Atoll.

Network Settings• Technology-specific network settings can be defined in the appropriate folders on the Parameters tab. They are differently managed

depending on each technology but are identical to the ones which are available in each single-RAT project.

GSM GPRS EDGE Networks• It is now possible to design, plan, and optimise 3GPP Multi-RAT networks in a single Atoll document and database. 3GPP Multi-RAT

networks can include GSM, UMTS, and LTE radio access technologies. For more information, see "3GPP Multi-RAT Networks" on page 10.• The project template dedicated to 2G networks has been renamed from GSM GPRS EGPRS to GSM GPRS EDGE.


• Antenna Hopping is now supported at the subcell level. In antenna hopping, the signal is successively transmitted on several antennas.As a consequence, a gain (defined per clutter class) is experienced on C/I values when antenna hopping is active.

• It is now possible to extend the allowed value ranges for subcell C/I and reception thresholds by adding an option in the Atoll.ini file.


• Following the introduction of the multi-RAT template, some predictions have been renamed in order to be consistent betweentechnologies.


• In order to remain consistent with other radio access technologies, neighbour planning is now accessible from the context menu ofthe GSM Transmitters folder.

• Inter-transmitter distances can be taken into account in the neighbour importance calculation by setting a distance factor.

• Frequency and Parameter Planning

• The subcell audit has been enhanced in order to fix values to respect their appropriate ranges.

• Intermodulation Interference Calculation (optional)

• You can now choose to activate or deactivate the calculation of third-order intermodulation interference by setting an atoll.ini option.• Using the same atoll.ini option used to activate or deactivate the calculation of third-order intermodulation interference, you can also

choose whether to limit the calculation of intermodulation interference to co-site transmitters only or to extend it to all interferingtransmitters.

Atoll AFP• The AFP progress interface has changed with the aim of giving more priority to the essential parameters dealing with AFP convergence.

A graph showing the cost evolution in real time is now displayed and detailed information about cost evaluation have been moved toother tabs.

• The IFP interface has been improved to provide more details about the evaluation of the cost. Additionally, tip text is now available onany selected value.

Network Capacity• Traffic Capture and Dimensioning

• In the Dimensioning/KPI dialogue, the distribution of services has been split in two parts: one for circuit-switched services, one forpacket switched services.

• If the user defines custom columns with ACP-specific parameters in the Transmitters, Repeaters, Sites, and Cells tables and defines themin the acp.ini file, ACP will use the set values as default values in a new optimisation setup.

• The process of defining the objectives used to evaluate the success of the optimisation has been improved.• Antenna-masking in the ACP has been improved and simplified, with the ACP automatically detecting supported propagation models and

offering several options for propagation models that are not natively supported.• The ACP now enables the creation of user-defined objectives.

UMTS HSPA Networks• It is now possible to design, plan, and optimise 3GPP Multi-RAT networks in a single Atoll document and database. 3GPP Multi-RAT

networks can include GSM, UMTS, and LTE radio access technologies. For more information, see "3GPP Multi-RAT Networks" on page 10.


• Modelling of dual-cell HSDPA is available. Transmitters can be defined to support dual-cell HSDPA. HSDPA scheduling is then carriedout per transmitter.

• Modelling repeaters and remote antennas is now possible in LTE. • The PDCCH interference is now weighted by the downlink traffic loads of the interfering cells, similar to the PDSCH interference.

However, you can set PDCCH interference to 100% like in the previous releases by adding an option in the Atoll.ini file.


• You can calculate the EIRP from Max Power instead of reference signal power when calculating signal level-based coveragepredictions through an option in the Atoll.ini file.


• By setting an option in the atoll.ini file, you can create a "Coverage by Aerial" signal level coverage prediction which lets you definethe display settings for repeaters and remote antennas independently of their associated transmitters.

• An effective service area analysis (DL+UL) coverage prediction is now available. This prediction shows the areas where a service isavailable in downlink and uplink depending on the downlink and uplink bearers of the service and their selection thresholds.

• Signal level coverage predictions, C/N coverage predictions, and control channel (RS, SS, PBCH, and PDCCH) signal quality coveragepredictions are only limited by the cell minimum RSRP. PDSCH signal quality, service area, throughput, and quality indicator coveragepredictions are limited by the cell minimum RSRP and the bearer selection thresholds of the lowest available bearer.

• For Coverage by C/(I+N) (DL), Coverage by C/(I+N) (UL), Service Area Analysis (DL), and Service Area Analysis (UL), it is now possibleto export the actual calculation results for each pixel to a text file.


• Atoll now identifies intra-carrier and inter-carrier neighbours at the end of the automatic neighbour allocation.• When the importance of neighbours is calculated, Atoll now takes a definable maximum distance between sites into consideration.• Atoll now enables the allocation of neighbours to individual cells.


• An Interference Matrices folder is now available on the Network tab of the Explorer window.• The Interference Matrices folder can contain more than one interference matrix.• Interference matrices can be calculated in Atoll or imported from external sources (text files).• Interference matrices can be exported to text files.• Interference matrices in the Interference Matrices folder can be used in the AFP for frequency and physical cell ID planning.• Interference matrices in Atoll are fully editable:

• Interference matrix entries can be modified, deleted, and added as required.• Interference matrices contain co-channel and adjacent channel interference probabilities which can be edited in Atoll.• New interference matrix entries can also be added to an existing interference matrix.

Network Configuration Using the AFP• Automatic physical cell ID planning is now integrated in the LTE AFP module. The basic physical cell ID planning in the LTE module (without

an AFP licence) is no longer supported. It can however still be made available by setting an atoll.ini option. The AFP uses wide-ranginginputs and a faster, more sophisticated algorithm for physical cell ID planning than the basic allocation feature.

• It is now possible to lock PSS ID and SSS ID separately for allocation by the AFP. This optional feature can be activated by adding a newfield in the Cells table. A document containing information about this feature is available on demand.


• It is now possible to set uplink and downlink lowest bearers for each service, hence defining a minimum required PDSCH and PUSCHC/(I+N) in order for the service to be accessible.

• Monte Carlo Simulations• Inactive mobiles are now listed in the simulation results. In previous releases, inactive mobiles were not listed because they do not

have any impact on the network load.• Uplink noise rise control (interference-based uplink power control) is now modelled. The difference between the maximum uplink

noise rise and the actual noise rise for a cell dictates whether the interfering mobiles in the neighbour cells must transmit less power(and therefore create less interference) or they can transmit at higher powers. The maximum PUSCH C/(I+N) is calculated duringMonte Carlo simulations and can be updated in the Cells table. This can also lead to an increase or decrease in the number of usersserved by the neighbouring cells in the uplink.







Network Settings• UE categories are now available. UE categories define the maximum downlink and uplink throughput capabilities of LTE user equipment.

They also define the highest uplink modulation and the maximum number of antennas supported by user equipment.• You can assign a UE category to each terminal type.• Atoll now fully supports the special subframe in TDD frame configurations. The DwPTS part of the special subframe is used for data and

control channel transmission.• Atoll now supports beamforming smart antennas in Monte Carlo simulations as well as coverage prediction calculations.• Modelling TDD LTE networks in Atoll requires a few more parameters than FDD LTE networks. TDD-specific parameters are hidden unless

there is at least one TDD frequency band defined in the Frequency Bands table. This allows users designing and planning FDD LTEnetworks to have a clear GUI, without TDD-specific parameters.

• It is now possible to define the numbers of frequency blocks belonging to each ICIC part of the frame through ICIC configurations. ICICconfigurations are used for static downlink and uplink ICIC based on fractional frequency reuse and PSS IDs.

• New reference signal EPRE calculation methods are now available: Calculated (equal distribution of unused EPRE), Calculated (with boost)which corresponds to a 3 dB boost in the RS EPRE with 2 transmission antenna ports and 6 dB boost with 4 ports, and Calculated (withoutboost).

• It is now possible to enter the reference signal EPRE and the maximum power for each cell independently. With this option, Atoll neithercalculates one from the other nor verifies the validity of the entered values.

• An effective service area analysis (DL+UL) coverage prediction is now available. This prediction shows the areas where a service isavailable in downlink and uplink depending on the downlink and uplink bearers of the service and their selection thresholds.

• Signal level coverage predictions, C/N coverage predictions, and preamble and pilot signal quality coverage predictions are onlylimited by the cell preamble C/N threshold. Traffic signal quality, service area, throughput, and quality indicator coverage predictionsare limited by the cell preamble C/N threshold and the bearer selection thresholds of the lowest available bearer.

• For Coverage by C/(I+N) (DL), Coverage by C/(I+N) (UL), Service Area Analysis (DL), and Service Area Analysis (UL), it is now possibleto export the actual calculation results for each pixel to a text file.

is locked, the AFP can only modify the preamble index such that it corresponds to the segment number of the cell.• You can instruct the WiMAX AFP to equally distribute the available preamble indexes in the network by setting an option in the atoll.ini

file.• Downlink and Uplink Permutation Zone PermBase Planning

Microwave Radio Links Networks• Atoll now permits the user to define parameters for the project that describe it and that can be used in reports exported in RTF.• Project-related information (such as the project author, the timestamp, and comments) can now be entered and saved with the ATL file.

Network Planning• You can change the position of the site and microwave link labels on the map.• In microwave link properties, you can define if the antennas installed on the sites are protected by radomes. The losses caused by the

radome can be defined in the antenna Properties dialogue.• Link properties have changed.

• Space diversity and the XPIC mechanism are characteristics defined in the configurations; they are no longer defined in the linkProperties dialogue.

• Selecting a radio on each site of the link has been enhanced. According to the defined frequency band and the operation mode, anassistant enables you to select an inter-channel spacing, the modulation configuration supported by the radio series and then, thecorresponding radio.

• You can select the standard or the maximum power that the radio can transmit. This parameter is taken from the radio seriesproperties of the selected radio.

• There are now more options available for formatting a report to be exported in RTF format, including the ability to include projectkeywords from the document description in the header and footer.

Quality and Availability Calculation Methods• How quality and availability objectives are selected has changed. By default, they are selected according to the microwave link rate and

its length. Afterwards, they can be selected according to the type of the objective.• Atmospheric gaseous attenuation can be now calculated following ITU-R P.676-6 and ITU-R P.676-7 recommendations.

Path Profile Analysis• In the Profile view of the Microwave Analysis window, Atoll can display a Fresnel ellipsoid for the diversity antenna installed at the

receiver.

Reliability Analysis• Performance objectives defined by G.828 recommendations can be taken into consideration in new Microwave Radio Links projects.

Reflection and Diversity Analysis• The separation between the main and the diversity antennas is taken into account in the calculation of waveguide and cable losses.

Analysis Report• In the microwave link analysis report, the nominal received signal level and the propagation results are detailed for the diversity antenna.

Link Budget Report• Atoll provides a new result in the summary section of the microwave link report. In addition to the average annual availability, the average

annual availability taking into account both rain and equipment failures is indicated in percentage of time.

Interference Analysis• You can now define a global threshold degradation. This threshold is used to indicate when a link is interfered. A link is considered to be

interfered when the threshold degradation caused by all interferers exceeds the global minimum threshold.• A calculation resolution can be taken into account when calculating interference.• How Atoll takes the shielding factor into consideration has changed. The shielding factor is taken into consideration when calculating the

interference received by the sites of the link. Only signal levels received from interferers are attenuated by the shielding factor.• Atoll now enables the user to either define a minimum resolution to be used when calculating interference or to use the minimum

resolution defined in the geographic data.

Frequency Planning• The Channel Arrangement tool has been improved. A new option enables you to display each half of the link in a colour assigned to the

half-band used on its site.

• The degradation threshold experienced by each site of the studied link as well as the received quality level are indicated as results of thesemi-automatic channel allocation. In addition, sorting features are now available in the Results dialogue. They can be sued to rank thelist of channels according to any parameter (cost, threshold degradation, etc.).

Network Settings• Transmission parameters are now available on the Parameters tab of the Explorer window. You can define the supported modulations,

digital trunks, throughputs, and connection types.

For each modulation, you can define the quality target (Eb/No)to be reached in order for the modulation to be used. You can either definethe Eb/No values for BER of 10-3 and 10-6 or take into account values calculated by Atoll.

IP technology is now supported when defining a digital trunk.

Atoll enables you to define all configurations supported by radios (the number of main channels, the number of standby channels,whether hot standby, space diversity, frequency diversity, or XPIC is supported).

• Atoll enables you to manage radio series. A radio series lists all configurations of radios belonging to it (i.e., the frequency bands in whichradios of the series can operate, the supported modulations, capacities and protection types). For each supported combination, you candefine global parameters such as transmission-related parameters and transmissions and reception losses. Each time you create a newradio, you have to define which radio series it belongs to.

The radio description has changed. Some parameters now depend on the radio series of the radio and others can be defined as a functionof BER.

• Adaptive modulation can now be modelled. Atoll enables you to define whether radios of the radio series support this operation mode.If the link can switch from one modulation to another one, you can select the supported modulations.

Atoll displays availability and quality results for each supported modulation in the microwave link analysis report.

• In order to define the range of channels to be excluded from the upper or the lower half-band, you can enter the first and last channel ofthe range separated by a hyphen.

• Through the Atoll.ini file, it is possible to define prefixes or suffixes to be used for naming channels. For information, see the AdministratorManual.
